statement not reached error

class a{
public static void main(String args[]){
int i=4;
while(true)
System.out.println("abc"); // if this is commented it compiles properly
System.out.println("aa");
}
}

Just as a comment, yes you are correct it only generates the
error when the statement cannot be reached.

while(true) is OK
whil(false) is compile error

i think that's because while statement is a block statement. unless you didn't provide {} for it , it can only execute one statement and if you have others it might not know what to do with it since braces were not provided.

just look at the code and see... how can the second statement be reached when the loop in the earlier statement can never end?
in fact if you'd written while (false) stat1;
it would have given the error for stat1
this holds true for loops generated thru... for(;true

and for(;false

too...
also, if (false) stat1 would compile! This provide the ability to conditionally compile the code...

that's supposed to be
for (; false; ) and for(; true; )!

Thanks a lot anshuman!!. I learnt a new concept.
